It's never too old to practice yoga. An old man teaches yoga for free three times a week in Hangzhou city, East China's Zhejiang province.

Le Mingchao, 72, one of the few senior yoga instructors in Hangzhou city, has taught around 20 students yoga since March 2015. All of his students are middle-aged, even elderly people, and among them the oldest is 81 years old.

"I want to help the elderly people participate in different activities. If needed, I will increase my courses," said Le in response to the increase in demand for yoga classes by the elderly.
